Role of Indole-3-butyric Acid or/and Putrescine in Improving Productivity of Chickpea (Cicer arientinum L.) Plants

A.A. Amin, F.A. Gharib, H.F. Abouziena and Mona G. Dawood

Abstract:
The response of chickpea (Cicer arientinum L. cv. Giza 3) to treatment with two plant growth regulators putrescine (Put) and Indole-3-butyric acid (IBA) at 25, 50 and 100 mg L-1 applied either alone or in combinations was studied. Spraying of Put and IBA either individually or in combination significantly increased the plant height, number and dry weight of branches, leaves and pods/plant and leaf area/plant at the two growth stages. Total photosynthetic pigments in fresh leaves were significantly promoted as a result of application of Put or IBA. Generally, application of Put and/or IBA at 100 mg L-1 produced the highest numbers of pods which resulted in substantially the highest seed yield. Put and IBA increased the seed yield by 21.3 and 19.2%, respectively, while the combination of Put at 100 mgL-1 and IBA at 50 mgL-1 increased it by 27.4%. Greatest increases in straw and biological yield/fed (38.3 and 30.4%, respectively) were noted with the combination treatment of IBA 100 mg L-1 plus Put at 100 mg L-1. Put and IBA significantly increased the nitrogen, phosphorus, potassium, total soluble sugars and total free amino acids in chickpea seeds over control, but the effects were less marked than those of their combination. This response was greater following treatment with IBA than with Put. It could be conclude that spraying Put or/and IBA on chickpea plants have promotion effects on the seeds yield criteria which have promising potential as sources of low-cost protein and minerals for possible use as food/feed supplements.
